Dry weight (g), concentration of total Fe ([Fe]t), concentration of 57Fe in excess ([57Fe]e) and content of 57Fe in excess (57Fee) in the leaves, stems and roots measured in Citrus aurantium seedlings.

Plants were grown for 21 days in Fe-sufficient (+Fe) or Fe-deficient (-Fe) nutrient solutions with the non-stressed (Ct) or the flooding treatment (S). For 57Fe determinations, plants were labelled immediately after treatments with 100 μM o,o-57FeEDDHA for 24 h.1Values for DW and [Fet] are the means of six independent plants per treatment (n = 6). Values for [57Fee] and 57Fee are the means of three independent experiments (n = 3). For a comparison of the means, an ANOVA followed by the Fisher´s least significant differences (LSD) test, calculated at the 95% confidence level, was performed. Different letters in the same row indicate significant differences between the different genotypes and treatments. Levels of significance are represented by P 0.05 (*), P 0.01 (**), P 0.001 (***) and ns (non-significant).Dry weight (g), concentration of total Fe ([Fe]t), concentration of 57Fe in excess ([57Fe]e) and content of 57Fe in excess (57Fee) in the leaves, stems and roots measured in Citrus aurantium seedlings.
